In the mid-1960s, U.S. Treasury vaults revealed a massive cache of nearly three million uncirculated Morgan silver dollars, the majority struck at the Carson City Mint in Nevada with the distinctive CC mintmark. These coins, produced from Comstock Lode silver between 1878 and 1893, had remained largely untouched in government storage for decades after the mint closed.

The Carson City Mint and Comstock Silver Origins

Congress authorized the Carson City Mint in 1863 to process silver from the Comstock Lode, the richest silver strike in American history located near Virginia City, Nevada. The facility opened in 1870 and struck silver dollars including Seated Liberty, Trade, and Morgan types until operations ceased in 1893. The CC mintmark on these coins directly ties them to Nevada’s mining heritage and the era when silver flowed from the Comstock region.

Discovery and Release of the GSA Hoard

During a 1964 inventory, officials identified approximately 2.9 million silver dollars still in Treasury holdings, with nearly 2.5 million bearing the Carson City mintmark. Congress authorized the General Services Administration to sell the hoard through a series of mail-bid sales beginning in 1972. The GSA sorted the coins by date and condition, placing many uncirculated examples in special hard plastic holders marked for Carson City. Sales continued through 1980, dispersing the coins to collectors while generating substantial revenue for the government.

Documented Quantities from the Hoard

• 1882-CC: 605,029 coins in the hoard out of 1,133,000 original mintage
• 1883-CC: 755,518 coins in the hoard out of 1,204,000 original mintage
• 1884-CC: 962,638 coins in the hoard out of 1,136,000 original mintage
• 1885-CC: 148,285 coins in the hoard out of 228,000 original mintage

Las Vegas Casino Connections to Carson City Silver Dollars

Many surviving Carson City Morgan dollars show evidence of circulation in Nevada gaming establishments, including Las Vegas casinos where silver dollars served as standard currency in dollar slot machines and on gaming tables for decades after the mint closed. As silver values rose in the 1960s, casinos faced shortages and transitioned to issuing their own private dollar tokens starting in 1965 under Nevada Gaming Commission regulations, with the Franklin Mint producing many of the early examples for properties across the state. This shift preserved the legacy of the original CC silver dollars while creating a new category of Nevada gaming collectibles tied to the same silver heritage.

Practical Takeaways for Collectors

Collectors seeking vintage silver bullion with Nevada ties should examine GSA-held Carson City Morgans for their documented provenance, original holders, and direct connection to Comstock silver and state casino history. These pieces offer tangible links to 19th-century mining and 20th-century gaming culture without reliance on modern market conditions.
